Resumen: Objetivos: El ictus constituye una causa muy frecuente de muerte, especialmente en el sur de España; se analiza la mortalidad intrahospitalaria asociada a ictus en un hospital andaluz de tercer nivel. Métodos: Registro de pacientes con ictus como diagnóstico en su informe de defunción en el Hospital Virgen de las Nieves de Granada durante 2013. Se utilizan además datos globales sobre altas en ictus y se comparan con iguales variables en síndrome coronario agudo (SCA). Resultados: Altas con diagnóstico de ictus 825 (96 defunciones, 11,6%); 562 isquémicos (44 fallecidos, 7,8%); 263 hemorrágicos (52 muertes, 19,7%). Los hemorrágicos, por tanto, tuvieron mayor mortalidad (OR = 2,9) y más precoz durante el ingreso (mediana 4 vs. 7 días, global 6 días), aunque los isquémicos fueron más ancianos y más pluripatológicos. Altas con SCA 617 (36 fallecidos, 5,8%); OR de mortalidad en ictus/SCA = 2,1. Un 23% de los fallecidos con ictus estaban anticoagulados cuando lo presentaron. El 60% de los ictus isquémicos y el 20% de los ictus hemorrágicos fallecidos tenían fibrilación auricular; solo el 35% de los pacientes con ictus isquémico y fibrilación auricular estaban anticoagulados. Conclusiones: El ictus supera al SCA en ingresos y mortalidad intrahospitalaria. El ictus hemorrágico supera al isquémico en mortalidad asociada. La anticoagulación crónica es frecuente en pacientes con ictus fatal; 2 tercios de los pacientes con ictus isquémico mortal y fibrilación auricular no estaban anticoagulados. Según nuestros resultados, optimizar la prevención en pacientes con fibrilación auricular podría impactar favorablemente sobre la mortalidad intrahospitalaria asociada al ictus. Abstract: Objectives: Stroke is a very common cause of death, especially in southern Spain. The present study analyses in-hospital mortality associated with stroke in an Andalusian tertiary care hospital. Methods: We gathered the files of all patients who had died at Hospital Universitario Virgen de las Nieves in Granada in 2013 and whose death certificates indicated stroke as the cause of death. We also gathered stroke patients discharge data and compared them to that of patients with acute coronary syndrome (ACS). Results: A total of 825 patients had a diagnosis of stroke (96 deaths, 11.6%); of these, 562 had ischaemic stroke (44 deaths, 7.8%) and 263 haemorrhagic stroke (52 deaths, 19.7%). Patients with haemorrhagic stroke therefore showed greater mortality rate (OR = 2.9). Patients in this group died after a shorter time in hospital (median, 4 vs 7 days; mean, 6 days). However, patients with ischaemic stroke were older and presented with more comorbidities. On the other hand, 617 patients had a diagnosis of ACS (36 deaths, 5.8%). The mortality odds ratio (MOR) was 2.1 (stroke/SCA). Around 23% of the patients who died from stroke were taking anticoagulants. 60% of the deceased patients with ischaemic stroke and 20% of those with haemorrhagic stroke had atrial fibrillation (AF); 35% of the patients with ischaemic stroke and AF were taking anticoagulants. Conclusions: Stroke is associated with higher admission and in-hospital mortality rates than SCA. Likewise, patients with haemorrhagic stroke showed higher mortality rates than those with ischaemic stroke. Patients with fatal stroke usually had a history of long-term treatment with anticoagulants; 2 thirds of the patients with fatal ischaemic stroke and atrial fibrillation were not receiving anticoagulants. According to our results, optimising prevention in patients with AF may have a positive impact on stroke-related in-hospital mortality.
